The Department of the Air Force awarded Houston geothermal company Sage Geosystems Inc. a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy “needed for a base to achieve energy resilience,” according to a news release. The Sage facility will be the first GGS facility in the world to generate electricity, and the system will be constructed at an off-site test well in Starr County, Texas.

”We are excited to partner with the U.S. Air Force on this geothermal demonstration project,” CEO of Sage Geosystems Cindy Taff says in a news release. “Next generation geothermal technologies, like Sage Geosystems’ GGS, will be critical in providing energy resiliency at U.S. military installations.”

In addition to the grant, the company will match the grant with an additional $1.9 million for the demonstration project. The collaboration with Sage is one of three geothermal pilot projects the DAF has initiated in regards to next-generation geothermal technologies in 2024.

“We feel this is the launch pad of helping not only the DoD but many other applications throughout global markets,” 147th Civil Engineer Squadron Commander Lt Col Christian Campbell says in the release.

According to the DAF, the possibility of a full-scale project at Ellington Field Joint Air Reserve Base in Houston could usher in a new era of clean power producing plants to help meet the requirements for bases.

“This initial contract is a step forward in the Air Force’s push for energy resilience,” Kirk Phillips, director of the Air Force Office of Energy Assurance, adds in the release. “This project will improve Ellington Field’s ability to maintain operations during electrical grid outages and be completely self-sufficient for their energy needs.”

The GGS process works by repurposing fracking technology to extract thermal energy from below the Earth’s surface.GGS also demonstrates the opportunity for the civilian sector by surpassing the intermittency challenges for solar and wind energy generation. GSS can also work towards minimizing land use, which enables the technology to be used in urban areas without relying on transmission line build outs that can be expensive.

“This project, and the future Department of the Air Force projects that it paves the way for, will help to assure that our national security needs are met by our installations during critical emergencies,” Phillips continues.

4 biggest challenges of Houston-based sustainability startups

Houston innovation awards

Six Houston-area sustainability startups have been named finalists in the 2023 Houston Innovation Awards, but they didn't achieve this recognition — as well as see success for their businesses — without any obstacles.

The finalists were asked what their biggest challenges have been. From funding to market adoption, the sustainability companies have had to overcome major obstacles to continue to develop their businesses.

The awards program — hosted by EnergyCapital's sister site, InnovationMap, and Houston Exponential — will name its winners on November 8 at the Houston Innovation Awards. The program was established to honor the best and brightest companies and individuals from the city's innovation community. Eighteen energy startups were named as finalists across all categories, but the following responses come from the finalists in the sustainability category specifically.

1. Securing a commercial pilot

"As an early-stage clean energy developer, we struggled to convince key suppliers to work on our commercial pilot project. Suppliers were skeptical of our unproven technology and, given limited inventory from COVID, preferred to prioritize larger clients. We overcame this challenge by bringing on our top suppliers as strategic investors. With a long-term equity stake in Fervo, leading oilfield services companies were willing to provide Fervo with needed drilling rigs, frack crews, pumps, and other equipment." — Tim Latimer, founder and CEO of Fervo Energy

2. Finding funding

"Securing funding in Houston as a solo cleantech startup founder and an immigrant with no network. Overcome that by adopting a milestone-based fundraising approach and establishing credibility through accelerator/incubator programs." — Anas Al Kassas, CEO and founder of INOVUES

"The biggest challenge has been finding funding. Most investors are looking towards software development companies as the capital costs are low in case of a risk. Geothermal costs are high, but it is physical technology that needs to be implemented to safety transition the energy grid to reliable, green power." — Cindy Taff, CEO of Sage Geosystems

3. Market adoption

"Market adoption by convincing partners and government about WHP as a solution, which is resource-intensive. Making strides by finding the correct contacts to educate." — Janice Tran, CEO and co-founder of Kanin Energy

"We are creating a brand new financial instrument at the intersection of carbon markets and power markets, both of which are complicated and esoteric. Our biggest challenge has been the cold-start problem associated with launching a new product that has effectively no adoption. We tackled this problem by leading the Energy Storage Solutions Consortium (a group of corporates and battery developers looking for sustainability solutions in the power space), which has opened up access to customers on both sides of our marketplace. We have also leveraged our deep networks within corporate power procurement and energy storage development to talk to key decision-makers at innovative companies with aggressive climate goals to become early adopters of our products and services." — Emma Konet, CTO and co-founder of Tierra Climate

4. Long scale timelines

"Scaling and commercializing industrial technologies takes time. We realized this early on and designed the eXERO technology to be scalable from the onset. We developed the technology at the nexus of traditional electrolysis and conventional gas processing, taking the best of both worlds while avoiding their main pitfalls." — Claus Nussgruber, CEO of Utility Global

Houston startup strikes deal to develop hydrogen production plant in Canada

hydrogen partnership

Houston-based cleantech startup Vema Hydrogen has reached a tentative agreement with Canada-based CHARBONE Corp. to develop a hydrogen production and processing plant in Québec.

The deal would couple Vema’s production of engineered mineral hydrogen with CHARBONE’s purification, compression and distribution capabilities.

Engineered mineral hydrogen, also known as orange hydrogen, is produced underground by accelerating naturally occurring geochemical reactions in iron-rich rock formations, according to the journal Energy & Environmental Science.

“Across high-value markets — from aviation and maritime fuels to industrial gases — there is incredible demand for Vema’s low-carbon [hydrogen]. Now, more than ever, we need a pathway to deliver these low-carbon fuels,” Pierre Levin, CEO of Vema, said in a news release.

The project would enable Vema to expand into emerging markets like low-carbon maritime and aviation fuel, e-fuels and power generation. Incorporating CHARBONE’s capabilities, the agreement would also support Québec’s hydrogen supply chain.

“The market is demanding high-value industrial gases, and our customers need cleaner, more reliable supply. By pairing Vema’s [hydrogen] feedstock with our purification and distribution capabilities, we’re strengthening Québec’s position as a regional hub for next-generation hydrogen,” Dave Gagnon, CEO of CHARBONE, added in the release.

Vema said in February that it had completed drilling of its first two pilot wells in Québec, making them the world’s first pilot well for orange hydrogen. It’s the first time Vema’s technology has been used outside a lab.

“This pilot will provide the critical data needed to validate [our hydrogen] at commercial scale and demonstrate that Quebec can lead the world in this emerging clean energy category,” Levin said. “The quality of the rock within our core samples is exactly what we expected and is very promising for hydrogen yields.”

Shortly before Vema carried out the pilot drilling, it signed a 10-year deal with California-based energy technology company Verne Power to supply clean hydrogen for California data centers. Over the course of the 10-year agreement, Vema will boost annual production of orange hydrogen to more than 36,000 metric tons.

“There is a robust market for baseload power generation across the U.S., where data centers are straining the grid,” Levin said. “As we power California’s fastest-growing markets with clean hydrogen, we look toward expanding our hydrogen to markets globally and supporting AI-driven power hubs.”

Vema, founded two years ago, raised $13 million in seed funding in 2025.

“The energy transition and emerging uses of hydrogen have spurred demand for clean hydrogen,” Levin said in its funding announcement. “However, existing decarbonized hydrogen production methods simply don’t work — they are too costly and energy-intensive. Vema is here to change that. It’s time to unlock a new era of scalable, low-carbon hydrogen.”

5 must-read Houston energy headlines: Veriten venture fund, ERock IPO + more

Trending News

Editor's note: The month of May brought big news for the Houston energy sector, including a flagship energy venture fund and IPO updates. Here are the five most-read EnergyCapital stories published May 14-29, 2026:

1. Houston investment firm closes $105M energy venture fund

Houston-based investment firm Veriten has announced the initial close of its second flagship energy venture fund with more than $105 million in capital commitments. Fund II will build on Veriten’s initial fund and aim to support “scalable technology solutions for energy, power and industrial applications.” Veriten is supported by over 50 strategic partnerships in the energy, power, industrial and technology sectors, including major players like Halliburton and Phillips 66.

2. Buoyed by $1.3B sales backlog, microgrid company ERock files for IPO

Another energy company in Houston is going public amid a flurry of energy IPOs. Houston-based ERock Inc., which specializes in utility-grade onsite microgrid systems for data centers and other customers, has filed paperwork with the U.S. Securities and Exchange Commission (SEC) to sell its shares on the New York Stock Exchange. The ERock filing follows the recent $1.9 billion IPO of Houston-based Fervo Energy, a provider of geothermal power that’s now valued at $7.7 billion.

3. Houston renewables developer signs agreement with Meta for new solar project

Houston-based EDP Renewables North America has signed a long-term power purchase agreement with Meta, the parent company of Facebook and Instagram, for its forthcoming Cypress Knee Solar project. The 250‑megawatt solar project will be built in Arkansas and is expected to come online by 2028. The company says the project will generate approximately $25 million in new revenue for Chicot County once operational.

4. Houston energy expert asks: Who pays when AI outruns the power grid?

For most of the past 20 years, U.S. electricity policy relied on predictable trends in demand. Electricity use, in most regions, increased gradually, forecasts were stable, and utilities adjusted the system in small steps. Power plants, transmission lines, and substations were generally added to reflect shifts in load, rather than growth, and costs were recovered through modest adjustments to customer bills. Growth in AI data centers has disrupted this model. A single facility can add as much electricity demand as a small town. That demand comes all at once, runs continuously, and has little tolerance for outages. If electricity service drops even briefly, computation stops, and services shut down. Ironically, data centers need reliable service, a point that their emergence is driving concern around for the rest of the grid.

5. Report shows geoscientists earn largest salary premium in Texas

A move to Texas bolsters earnings for some, and a new SmartAsset study has revealed the top professions where the median annual earnings in the Lone Star State exceed the national median. According to the report's findings, geoscientists have the biggest "Texas premium" and make a $159,903 median annual salary. Texas' salary for geoscientists is 61 percent higher than the national median for the same position (after adjusting for regional price parity).
